What goes into glycolysis?
1 glucose
What is glucose’s molecular structure?
C6H12O6
What is the first step of glycolysis?
Invest 1 ATP —> ADP + P + energy
What happens next?
Phosphorylate 6th C of Glucose molecule
What new molecule is formed?
Glucose 6-P
What happens to the Glucose 6-P?
Isomerization
What new molecule is formed from the isomerization?
Fructose 6-P
What happens next?
Invest 1 ATP —> ADP + P + energy
What happens to the Fructose 6-P?
1st C is phosphorylated
What molecule forms after Fructose 6-P is phosphorylated?
Fructose 1
What happens to the Fructose 1
6-P?
What happens to the DHAP?
Isomerization into G-3-P
What is the molecular structure of G-3-P?
They’re mirrored:
P~C-C-C
C-C-C~P
What happens to the G-3-Ps?
Oxidation
What is the “taxi-cab” molecule?
NAD+
What does the taxi-cab molecule do?
Takes G-3-Ps electron/proton
What does the G-3-P molecule become?
BPG
What is the molecular structure of BPG?
Mirrored:
P~C-C-C-P
P-C-C-C~P
What happens to the BPG molecules?
Weak bond broken: P
What do BPGs become?
3PG
What is the molecular structure of a 3PG?
Mirrored:
C-C-C-P
P-C-C-C
What happens to 3PGs?
Rearrangement
What is the molecular structure of 2PG?
P
|
C - C - C
What happens to the 2PG?
Loses H2O
What molecule does the 2PG become?
PEP
What happens to the PEP?
P + energy + ADP —> ATP
What do PEPs become?
Pyruvates
What comes out of glycolysis?
4 ATP
